Answer:
4x+6
Step-by-step explanation:
Perimeter (P) = 2l+2w
w=x+3
l=x
P=2x+2(x+3) --> 2x+2x+6
Combine like terms: 4x+6
Answer:
1. x =8
2. x=9
Step-by-step explanation:
Since these figures are parallelograms, the opposite sides are equal.
1. 6 = 2x-10
Add 10 to each side
6+10 = 2x-10+10
16 = 2x
Divide each side by 2
16/2 = 2x/2
8 =x
2. x+14 =23
Subtract 14 from each side
x+14-14 = 23-14
x = 9
